Amauronematus nuorbinjargi Saarinen, 1949: 55–62 .

Diagnosis

Females can be identified based on the colour pattern. Median mesoscutal lobe and mesoscutellar appendage are at least partly black, the first tergite is usually completely black and subsequent tergites with sharply decreasing black area (if the first tergite is mostly pale, then subsequent tergites are completely pale). Males have similar colouration, but might not always be distinguishable from, for example, the males of E. rufa .

Female

6.8–8.8 mm ( Schmidt 1997). Pterostigma usually pale, brown or centrally paler than externally; hind femur extensively pale, usually only dorsally black; hind tibia black or anteriorly and posteriorly pale or brown; usually first tergite completely black and subsequent terga with black flecks decreasing in size, sometimes abdomen nearly completely pale; sterna, hypopygium, and valvifer 2 pale; cerci extensively pale at least basally; valvula 3 extensively pale or brown; valvula 3 asymmetrical in lateral view, ventrally more distinctly curved than dorsally.

Male

5.5–7.0 mm (this study; Schmidt 1997). Pterostigma centrally paler than externally; hind femur and tibia usually extensively pale (only dorsally black), sometimes nearly completely black; first tergite completely black and subsequent terga with black transverse lines decreasing in size; all sterna pale.

Genetics

COI

Based on 8 specimens, maximum within-species distance is 0.61% and the nearest neighbours, diverging by a minimum of 0%, are Euura amicula , E. betulae , E. histrio , E. rufa , E. septentrionalis , E. striata , E. tenuis , and E. tota .

Nuclear

Based on 8 specimens, maximum within-species distance is 0.5% (0.43% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.5%, is Euura histrio .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Sweden.
